Investigatedin the microwave range radiophysical characteristics of cold plasma gas discharge andelectromagnetic characteristics of the U-shaped loop and a straight rod plasma emitters (PE)performed on the basis of the plasma. Evaluated in the meter wavelength range ofconductivity of cold plasma and the relative permittivity. In FEKO software environment,taking into account these data are simulated and studied loop and a straight rod PE. It wasfound that for positive values . r , loop PE provides more bandwidth than for negative values.The frequency range of the loop PE through a cold plasma is about four times larger in termsof VSWR <2 and three times - in terms of VSWR <5, than for the same emitter configurationof aluminum. When calculating the effective loop PE with positive values . r of PE efficiencyis 50-60%. For rod PE calculated efficiency does not exceed 20%.Downloads
